Abstract
The invention relates to a method of separating solid particles, using a magnetic fluid, wherein the magnetic fluid is passed through a magnetic field for the purpose of changing the effective density of the magnetic fluid, and the particles are separated into fractions of different density. The present invention further relates to device for separating solid particles, using a magnetic fluid.
